PULIiING-OVER MACHINE.
Specification of Letters Patent.
Patented Oct: 24, 1916.
Application filed February 1, 1916. Serial No. 75,576.
To all whom it may concern:
Be it known that I, ARTHUR BATEs, a subject of the King of England, residing at Leicestershire, England, have invented certain Improvements in Pulling- Over Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.
This invention relates to pulling-over machines and is herein shown as embodied in a machine of the type shown .and described in United States Letters Patent No. 1,029,387, granted June 11, 1912, on application of Ronald F. McFeely.
The object of this invention is to extend the field of utility of that machine by adapting it to perform operations heretofore performed by hand or with the aid of apparatus not comprised inthe machine.
In the manufacture of shoes the work comes to the pulling-over machine with the upper and innersole assembled upon the last alternatively, to effect this preparatory forward pulling of the upper by the use of the apparatus shown in United States Letters Patent No. 1,139,613, granted May 18, 1915, on application of Pearl J. Wentworth. The present invention provides for combin ng this preliminarypulling of the upper with the pulling-over operation by ut1l1z 1ng the toe gripper of a pulling-over, machine and providing an abutment suitablylocated with relation to the said gripper to enable the last to be fulcrumed thereon for pulling the upper, after which thetupper is arranged in the side grippers of the pulling-over machine and those grippers closed whlle .the toe gripper continues to hold the upper. This fully conserves the forward pull and saves one handling of the shoe. I
A feature of this invention consists lIl the combination with a'power-operated gripper mechanism' comprising a yieldingly closed toe gripper which normally comes to rest with the jaws open, of manual means for causing said mechanism to close the aws, and an abutment located in relation to said gripper to permit the last to be ful- J'crumed thereon for pulling the upper.
A further feature of the invention consists in a pulling-over machine comprising separately, and an abutment arranged with relation to said toe and side grippers topermit the shoe last to be fulcrumed thereon for pulling the upper between the toe gripper and the last and carrying the sides of the upper into the open jaws of the side grippers.
These and other features of the invention including certain combinations of parts and more important details of construction will now be described in connection with the accompanying drawings and will then be pointed out in the claims.
Figure 1 of the drawings shows a side elevation of a pulling-over machine partly in section and equipped with the present improvement. Fig. 2 shows a detail of the toe gripper controlling mechanism. Fig. 3 is a vertical section through the toe gripper.
The illustrative machine as a whole is constructed substantially in accordance with the disclosure in said McFeely patent and comprises a .sole rest 1 against which the bottom face of a shoe is adapted to be positioned between a toe gripper 2 and side grlppers 4C. The grippers are suspended from updraw levers pivoted on the fulcrum rod 5 and connected at their rear ends with updraw cams located on the cam shaft 6 a portion of the frame of the machine while the gripper bar 10 is forced downwardly to bring the surface 12 into engagement with the outer face of the movable gripper f jaws as shown in Fig. 3. A spring 13 is arranged within the gripper casing in posi-- tion to become compressed by thejaw opening movement of bar 10. When the spring is permitted'to do so, it expands and forces the bar upwardly, moving a closing roll 14 along the inner face of the movable gripper jaw to rock that jaw for 'gripp1ng the stock- This organizationof gripper mechanism is well known and does not require more detailed description.
In accordance with the illustrative embodiment of this invention, the rear end of the toe, gripper lever 15 is connected to its operating cam 16 through a slide 18 that has a movable connection with a rod 20, the rod extending upwardly through a knuckle on the rear end of the lever 15 and carrying a spring 22 that is under compression and through. which downward movement .of the rod is transmitted yieldingly to the lever for effecting upward movement of the gripper the front end of lever 15, depressing'the rear end of the lever together with the rod 20 and block 24. i As before explained, such upward movement of the gripper bar 10 effects the closing of the toe gripper aws.
The guidew-ay within which block 24 moves in slide 18 is long enough to permit all the movement required for closing the gripper jaws uponthethinnest stock presented to the machine. The latch 25 is controlled by one arm of a rock-shaft 30 the other arm of which is connected by a rod 32 with a lever 34 fulcrumed at its rear end and provided with a foot pedal atits front end.
In using the invention the operative presents an assembled shoe with the'toe endof the upper between the jaws of the toe gripper as shown in full lines in Fig. 1 and by pressure of his foot on the pedal of lever 34 withdraws the latch'25 from the projection 26 of the block 24 and thereby allows the spring 13'to close the toe gripperQ'For permitting the last to be fulcrumed and moved relatively to the toe gripper, the toe gripper f is provided on its rear face with a leg 35 thatprojects backwardly and downwardly intoposition to be engaged by the shoe bottomat a distance from the end of the toe. :iuex'cess of .the'width of the channel and feather formation of a welt shoe innersole.
The location thus provided for the insole engaging face of the leg has the advantage that injury to the channel and feather formation of the insole is avoided and that it locates the fulcrum forthelast at such a distance from the gripper jaws that a long pull on the upper forwardly can be obtained for taking the slack out of a loose upper. After closing of the toe gripper has been elfected in response to the pedal motion, the operative swings the shoe from the full line position toward the dotted line position in Fig. 1, causing the last to fulcrum on the leg 35 andthe'reby effecting substantially the same forward pull upon the upper which it has been customary to effect by the use of hand pincers or the apparatus of said Patent No. 1,139,613. The described rearward and up-v ward movement of the shoe to the dotted line position in Fig. 1 brings it against the sole rest'l and locates the sides of the upper inposition to be seized by the said'gripp'ers. Those grippers closeupon the upper in re sponse to pressure upon the startlng treadle of the machine (not shown) and thereafter the grippers and other portions of the machine cooperate to pull over the shoe as explained in theMcFeely patent.
In the power operation of the machine the slide 18 is moved downwardly by cam 16, and during this movement the face 27 of latch 25 engages the projection 29 of the block 24 to effect downward movement of the block and the rod 20, and the operation of the updraw lever 15 for raising the toe gripper. During the return or upward movement of the slide 18 after the pulling operation, the latch 25 is restored to engagement with the projection 26 by the action of a spring 31 which is shown in Fig. 1, said spring 31 also serving the purpose of a lifting spring for the pedal lever 34.
Having explained the nature of the invention and described an illustrative embodiment of the invention and how it may be used, I claim as new and desire to secure by Letters Patent of the United States 1. A pulling-over machine having, in
combination, a power-operated gripper ilo mechanism including a yieldingly closed toe gripper and means to bring the toe gripper to rest with the gripper jaws open, manuallycontrolled means for closing the jaws of the toe gripper, and an abutment located in relation to said gripper to permit the shoe last to be fulcrumed thereon and rocked with relation to the gripper for pulling the upper lengthwise of the last.
2. pulling-over machine having, in combination, a power-operated gripper mechanism including yieldingly closed side and toe grippers and means to bring. the grippers to rest with the jaws open, manually controlled means for closing the jaws of the toe'gripper while the jaws of the side grippers remain open, and an abutment arranged with relation to said too and side grippers to permit the shoe last to be fulcrumed thereon for pulling the upper between the toe gripper and the last and carrying the sides of the upper into the open jaws of the side grippers.
3. In a pulling-over machine, the combination with power-operated toe and side grippers, of manually'controlled means for causing the toe gripper to seize the upper, and a leg projecting from the toe gripper downwardly and backwardly into position to engage a Welt shoe innersole inside the channel and arranged to permit the shoe last to be fulcrumed thereon for pulling the upper between the toe gripper and the last as the shoe is moved into position for the upper to be seized by the side grippers.
4.. In a pulling-over machine, the combination with a toe gripper, of a last engaging abutment extending from the toe gripper downwardly and rearwardly into position for engagement with the innersole of a welt shoe at the inner side of the channel.
5. In a pulling-over machine, the combination with a power-operated gripper mechanism including a jaw closing spring, an updraw lever, a latch, and a cam through which the closing spring is put under tension and held and which comes to rest with the closing spring under tension, of manually controlled means for releasing the latch to permit the spring to close the jaws.
6. In a pulling-over machine, gripper operating mechanism including an updraw lever, a cam slide, a block movable in the cam slide and connected to the lever, a latch pivoted in the cam slide and normally holding the block in an operative relation to the slide, and manually controlled means for operating the latch. 7
